THIS MAGAZINE DOESN'T FIT THE SINGLE STACK 1911 A1.

NOT COMPATIBLE IN SOME OF THE PARA P16.40 WITHOUT MODIFICATIONS. I have been told it works in the Para Ordnance 16.40 LDA with no modification. It will work in the Para P16.40 Pro Custom WITH SLIGHT MODIFICATIONS. This is what customers told me they did to make them work in the Para P16.40:

Yesterday my magazines arrived and to my disappointment they didn't fit. I could see that they were shorter but not by much. The first thing I did was take off the ACT base plate and put on the stock pro custom base plate. After doing this they were very close to fitting, but still did not fit. I came to a crossroads where I had to decide if I was going to send them back or make them fit. I am an experienced woodworker but I have very little experience with metal. I packaged the magazines back up and was ready to send them back. I started thinking, ... if I screw one up oh well.

I took the magazine catch out of the gun and inserted the ACT-Mag with Para base plate and saw that the mag catch hole in the magazine was slightly off. I grabbed some sandpaper and a set of small files and slowly started opening the mag catch hole little by little. After about 30 minutes of filing a little and checking I had a magazine that locked in place. I slowly started to polish up my marks all the wall to 1000 grit sandpaper. I ended up widening the mag catch hole towards the top of the magazine by .0310 of an inch. The stock ACT-MAG magazine has an opening of 0.1345 inches I widened it to .1655 inches.

So here is the breakdown: The ACT-Mag base plates must be moved over to your stock pro custom magazines. The stock pro custom base plates need to be moved to the ACT-Mag. Leave the spring and followers in their positions. The new magazines sit slightly and I mean slightly lower. I have been feeding practice rounds through them and I will be honest they feed better than the stock mags, nice and smooth. So if you buy (2) magazines and you have (2) stock pro custom magazines you will end up with (4) functional magazines. Based on my measurements you should be able to order Dawson Precision base plates and have them fit.

This is from a customer with a Para P16-40 limited no magwell (built in 2011):

For the "Limited" model it works without any magazine modifications. The mag release may need to be replaced if it fits too loose. I say "may" because when I tried the mag in my Black ops it stayed locked with the stock mag release. The stock mag release has a small tab and the Act-Mag kept falling out (in the Para P16-40 limited no magwell built in 2011). Once I replaced the mag release with the Guncraft aftermarket release with the larger tab, it stayed locked and secure.

I doubt this review will help anyone else, but I wanted to pass along how this mag worked for me when others would not. I built a one of a kind pistol, a Taurus PT24/7 Pro in 10mm. It was the 45 ACP version, and with some fairly minor work, I was able to convert the 40 caliber slide/barrel to 10mm. The problem I ran into using the OEM 45 ACP mag or even a Mec-Gar P14 mag was fail to feed, especially with JHP ammo. Doing some research, I found the Armscor 40 cal mag was supposed to work for 10mm for a similar pistol. The price here was better than anywhere else- when you could find one- so I ordered a couple. I was pleasantly surprised how my first mag of 16 JHP rounds fed perfectly. Service here was great, shipping was fast and reasonable. I would definitely buy from Greg Cote LLC again.
